This invention relates to a deodorant, its preparation method, and its application, belonging to the field of deodorization technology. The invention provides a deodorant preparation method, specifically involving the following steps: a mineral-based deodorizing carrier, anhydrous calcium chloride, magnesium stearate, calcium peroxide, ferrous sulfate, basic copper carbonate, zinc oxide, and mesoporous silica are orderly mixed to obtain a composite powder. This powder is then mixed with a sodium silicate aqueous solution, kneaded, pressed into shape, and cured to obtain a raw blank. The raw blank is then immersed in a composite treatment solution containing silica sol, a silane coupling agent, and nano-titanium dioxide. After removal, it is dried and heat-treated to obtain the deodorant. The deodorant prepared by this invention can be applied to kitchens, bathrooms, and shoe cabinets, exhibiting excellent deodorizing effects.

The application is suitable for the technical field of wastewater treatment and resource recovery, and provides a resource treatment method for electroplating waste liquid, which is aimed at the waste liquid containing copper sulfate and sulfuric acid generated in the copper electroplating process, copper sulfate is generated by adding copper oxide, copper hydroxide or copper carbonate and the like into the waste liquid to react with free sulfuric acid in the waste liquid; then, the saturated copper sulfate solution after reaction is controlled in speed and cooled to crystallize, and high-purity copper sulfate crystals are separated; the crystallization mother liquor can be recycled to the reaction step to further improve the recovery rate, and finally, the tail liquid enriched with impurities is subjected to pH adjustment and ion exchange resin adsorption treatment to realize standard discharge. The application can efficiently convert sulfuric acid and copper ions in the waste liquid into electronic-grade copper sulfate products which can be directly reused in the electroplating process, realizes high-value recovery of resources, and reduces disposal cost and environmental pressure.
